Resumen del Recurso

Genome -- Contains all genetic instructions
  1. Chromosome -- Makes up the Genome, made of DNA
    1. DNA -- Tightly bound, Double-helix structure that forms Chromosomes and contains Genes
      1. Double-helix -- Two strands of alternating sugars and phosphates with nitrogenous bases lying like rungs on a ladder, connecting the strands. These strands resemble a staircase, so they are called 'Double-helix'
        1. Nitrogenous Bases -- Composed of Adenine & Guanine (Purines) as well as Thymine & Cytosine (Pyrimadine)
        2. Genes - Sequences within DNA that act as instructions to create proteins or do not create proteins
          1. Transcription - Creates RNA out of DNA template
            1. RNA -- Single strand structure that is involved in protein synthesis. Contains the nitrogenous base Uracil, instead of Thymine
              1. Messenger RNA (mRNA) -- Single strand sequence that contains Codons/Exons (but not Introns) for creating specific Amino Acids
                1. Single strand -- One strand of alternating sugars and phosphates with nitrogenous bases between them
                  1. Translation -- Process within the Ribosome (created from rRNA) that uses instructions (from mRNA) to create polypeptides from amino acids (carried by the tRNA)
                    1. Polypeptide -- When there are many Amino acid's within a Polypeptide, Proteins are created
                      1. Protein -- Complex structure that performs many functions for the human body
                    2. Exons & Introns -- Exons are genes that make proteins, they become mRNA. Introns are genes that don't make proteins, they get pulled out of the RNA sequence
                      1. Codon -- Sequence of nucleotides on an mRNA strand
                      2. Transfer RNA (tRNA) -- Carries Amino acids to ribosomes for Translation
                        1. Anticodon -- Complementary Codon to a specific Codon on the mRNA strand
                          1. Amino acid -- Make up Polypeptides
                          2. Ribosomal RNA (rRNA) -- Contains instructions to create Ribosomes for Translation
